(1)  Information
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ

This is the second version of $$$'s Adlib Tracker. It supports
Adlib Soundcards or soundcards with OPL2 Chipset (f.i. Soundblaster).
It needs about 128k of conventional memory and a 386 CPU, a compatible VGA
and a mouse.


What did I change in version 1.1 ???

 mhm...

 - now supporting RAD and HSC of coz!
 - new effect (command 3)
 - debugged the slide-error
 - debugged the memory allocation-error
 - released source and object of my player
 - new graphics analyzers (too cheap!!!)
 - completely recoded mouse-control (know its a bit faster I think !?)
 - verification on all sensible actions
 - fast forward with right mouse button

 - new demotunes from BiRD, MADNîSS and ANiMAL... thank you dudes!!!!

 - thats all I think...






(2)  Basics
ÄÄÄÄÄÄÄÄÄÄÄ

This version of AMUSiC supports the following formats:

 AMD - our Adlib Module format (packed and linear)
 SA2 - Surprise Adlib Tracker (Verion 2)
 HSC - Adlib-Tune-Format by Chicken
 RAD - Reality Adlib Tracker

 INS - Screamtracker Instrument
 AIE - Adlib Instrument format by Ryu/D+P+S

Information about the supported song commands or keyboard shortcuts are
provided in the online help (while pressing [F1] in the editor).

Is there anythin else to tell ya???   Dont think so!










(3)  Coders stuff
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ

If you want support Adlib music in your project, you can use our modules of
course. If you want, you can use the provided objectfile to play amd's.


Amusic supports two kinds of modules. The packed module and the normal
module format. The normal format is easier to code but modules are bigger
in size (often 10 times bigger!!!). Its up to you!!!



Adlib-MOD-Format: (c)23.8.1995 - 20:10:30 by Conqueror :)
-----------------
 hex  -  dec  -  function

 000h      0     name of song + nullbyte
 018h     24     name of autor + nullbyte
 030h     48     [...]  26 instruments (26*34 byte)
 3A4h    932     songlen
 3A5h    933     number of patterns-1
 3A6h    934     patterntable (128 Byte)
 426h   1062     id: "<oīQUîRoR"
 42Fh   1071     version 10h=normal module
			 11h=packed module

if the module isn't packed:

 430h   1072     all patterns (count*9*3*64 Bytes)

 END!!!


if the module is packed:


 430h   1072     table with Trax (ptncount*9*2)

- A pattern is divided into 9 tracks. Here comes a table that contains a
  number (offset) for each track saved in the file.
  This is because many tracks in the song can be identical copies of only
  one track saved in the file.

 xxxx   xxxx     number of trax  (WORD)
 xxxx+2 xxxx+2   [...] traxdatas

 END!!!



A track is written in the following manner: First comes a word that contains
the position of the track in song. (pattern*9+tracknr)
Then follows the events. One event takes 3 bytes. But empty events takes
only 1 byte ! You can distinguish real events from empty events
with the most significant bit of the first saved byte of the event.
If the bit is zero than you have a real event. But if the bit isn't zero
than you have to create some empty events in your current track. To get
the number of empty events just read the lower 7 bits of the byte.

Got it??? Hope so!!!


Here comes the format of an event:


 BYTES: x,y,z:

 xxxxxxxxyyyyyyyyzzzzzzzz
 000011122222333354444444

 0 - pitch of the event (0-12)
 1 - octave of the event (0-7)
 2 - instrumentnumber of the event (0-26)
 3 - eventcommand (0-9)
 4 - parameter of the command (0-99)

 5 - if this bit is turned on and the file is a packed module than 4 stands
     for the number of empty tracks. But you already know that!!!



Note: Read the event from the file in this direction:

	z y x     !!!!





Here comes the instrument format of the modules:

(decimal offsets)

0-22 Name
  23 Mod-Charakt.
  24 Mod-Amplit.
  25 Mod-AD
  26 Mod-SR
  27 Mod-Waveform
  28 Carr-Charakt.
  29 Carr-Amplit.
  30 Carr-AD
  31 Carr-SR
  32 Carr-Waveform
  33 Conntect





;-------

I am too lazy now to explain the object code. I give you some sourcecodes
in PASCAL and ASSEMBLER !  (Can bee found in sources-directory.)



But, what you perhaps need to know is the structure of the work buffer:


WrkBuff_TrackBase	equ 0     	;PRiVAT!!!
WrkBuff_TrackPtr	equ 480h	;PRiVAT!!!
WrkBuff_TrackDelay	equ 492h	;PRiVAT!!!

WrkBuff_CurrPtn		equ 49Bh	;
WrkBuff_CurrLine	equ 49Ch	;
WrkBuff_SongDelay	equ 49Dh	;
WrkBuff_CurrSpeed	equ 49Eh	;
WrkBuff_CurrEvent	equ 49Fh	;
WrkBuff_LastEvent	equ 4A4h	;
WrkBuff_CarrVol		equ 510h
WrkBuff_ModVol		equ 519h

WrkBuffSize equ 522h

Keep in mind: ALL DATAS ARE READ ONLY!!!
